The seemingly self-destructing Yankees received some good news Tuesday, when an MRI exam on Mark Teixeira’s injured left wrist showed only inflammation and no structural damage.

He received a cortisone shot after being examined by team physician Dr. Christopher Ahmad along with Dr. Melvin Rosenwasser at New York-Presbyterian Hospital and will be reevaluated in three days, according to the Yankees.

The first baseman aggravated an already sore wrist diving for J.J. Hardy’s hard ground ball in Monday’s 5-4 loss to the Orioles and took himself out of the game. The Yankees and manager Joe Girardi feared the worst, but Teixeira was cautiously optimistic and said his level of concern was “low.”

Teixeira added he suffered a similar injury in 2009, got a cortisone shot and was fine for the rest of the season.

For now, if the team doesn’t make a move by Tuesday’s 4 p.m. non-waiver trade deadline, it can use Nick Swisher at first base, leaving Eric Chavez and Jayson Nix to fill in for the injured Alex Rodriguez at third, with Ichiro Suzuki in right field and Raul Ibanez and Andruw Jones in left.

Teixeira said he first felt pain in the wrist during his third at bat Sunday against Boston, but he chose to play Monday partially because the Yankees, who have lost 8 of 11, were already shorthanded.
